CROSS-REFERENCE TO RELATED APPLICATION

The present application is a continuation of U.S. Non-Provisional application Ser. No. 15/691,213, entitled LONGITUDINAL CRASH BEAM RECEIVER, filed Aug. 30, 2017, which claims priority to U.S. Provisional Application No. 62/384,298, entitled ELECTRIC VEHICLE COMPONENTS, filed on Sep. 7, 2016, which is hereby incorporated by reference in its entirety for all purposes.

BACKGROUND OF THE INVENTION

Vehicle manufacturers have added a number of new structural features to vehicles to improve safety and/or performance. Many of these structural features are applicable to electric, hybrid, and non-electric vehicles equally, while others place a greater emphasis on the vehicle motor type, such as a vehicle base plate with increased thickness for protecting an electric car battery over a specific region of the vehicle. Structural improvements that increase either safety or performance without a significant compromise of the other remain important objectives of vehicle manufacturers.

Electric vehicles are becoming an increasingly viable alternative to traditional vehicles with internal combustion engines. Electric vehicles may have advantages in their compactness, simplicity of design, and in being potentially more environmentally friendly depending on the means by which the electricity used in the vehicle was originally generated. The prospect of using renewable energy sources to power automobiles in place of gasoline has obvious advantages as oil reserves across the globe become increasingly depleted.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present disclosure relate to a longitudinal crash beam situated in an electric vehicle for reducing the effects of a vehicle collision. The crash beam, along with other surrounding components coupled with the crash beam, are designed specifically to allow the crash beam to initiate a self-collapsing process in the event of a vehicle collision. The self-collapsing process is triggered by the application of a longitudinal force to a set of impressions positioned along the outside surface of the crash beam. The set of impressions are designed to fold simultaneously to ensure that the crash beam deforms and folds onto itself instead of folding laterally or vertically. Components surrounding the crash beam that are designed to aid the self-collapsing process of the crash beam include a crash beam receiver, a crash wall, a front securement member, a middle securement member, a rear securement member, and a crash tower. These components are described in further detail below.

Safety benefits of the crash beam include, but are not limited to: (1) increased rigidity of the vehicle, (2) increased absorption of energy, and (3) increased linearization of energy/force stemming from a front impact to the vehicle such that energy can be channeled through the crash beam receiver toward the body structure and/or chassis, lessening the potential impact applied to the vehicle battery and to passengers in the vehicle. For electric vehicles, an increased emphasis is placed on protection of the electric battery as damage to battery cells can cause explosion and fires within the vehicle. The problem is compounded due to the large amount of space batteries must occupy within electric vehicles in order to maintain practical driving ranges. Therefore, vehicle alterations that channel energy away from the vehicle battery are advantageous.

The crash beam described herein may be an aluminum casting part that is manufactured as a single integrated piece. In other embodiments, the crash beam comprises multiple different manufactured components that are later fastened together. Furthermore, the crash beam need not be aluminum but may be manufactured from a wide range of materials that are either currently available (such as carbon fiber or steel) or will be developed in the future.

Embodiments of the present disclosure also relate to a crash beam receiver for coupling to the crash beam. The crash beam receiver includes a plurality of surfaces that are coupled together to form a hollow opening for receiving the crash beam. The crash beam receiver also includes a gate structure for providing a stopping point for the crash beam when the crash beam is inserted into the crash beam receiver. The gate structure includes a left gate, a right gate, and a protrusion structure that help to linearize the self-collapsing process of the crash beam in the longitudinal direction. The protrusion structure has a certain thickness such that the crash beam is caused to collapse inward toward its center.

FIG. 1 illustrates a generalized transportation apparatus 100, according to an embodiment of the present disclosure. Transportation apparatus 100 may include any apparatus that moves in distance. Examples of transportation apparatus 100 may include a vehicle such as a car, a bus, a train, a truck, a tram, or any other type of vehicle; may include a vessel such as a boat, a ship, a barge, a ferry or any other type of watercraft; may include an aircraft such as an airplane, a helicopter, a spaceship, or any other type of aircraft; or may include any other transportation apparatus. In some embodiments, transportation apparatus 100 is an electrical automobile. As shown, transportation apparatus 100 may include a cabin 150 with a volume.

As shown in FIG. 1, transportation apparatus 100 may comprise one or more steering wheels 152 in cabin 150. Although only one steering wheel 152 is shown in FIG. 1, this is not intended to be limiting. In some examples, transportation apparatus 100 may include more than one steering wheel 152. For example, it is contemplated that transportation apparatus 100 may be an aircraft that comprises at least a main steering wheel 152 for the main pilot and at least a secondary steering wheel 152 for the co-pilot.

As also shown in FIG. 1, one or more users 154 may be arranged to occupy their corresponding positions in cabin 150. Users 154 may include one or more drivers that control the movement or navigation of transportation apparatus 100, one or more passengers, and/or any other type of users 154. In this example, user 154 a is a driver that controls the driving of transportation apparatus 100, while other users 154, e.g., users 154 b-d, are passengers. As still shown, there may be multiple rows of users 154 within cabin 150 of transportation apparatus 100.

FIG. 2 illustrates a perspective view of a front region of an electric vehicle 100, according to an embodiment of the present disclosure. The electric vehicle 100 includes a crash beam 102 oriented in the longitudinal direction with one end directed toward the front of the electric vehicle 100, possibly coupled to the bumper, and the other end directed toward the rear of the electric vehicle 100. Coupled vertically above to the crash beam 102 are a front securement member 194, a middle securement member 195, and a rear securement member 196. The middle securement member 195 and the rear securement member 196 are coupled directly to a crash tower 190 while the front securement member 194 is coupled to a longitudinal beam 192 which is coupled to the crash tower 190.

In some embodiments, the crash beam 102 interfaces with and is coupled to a crash beam receiver 160. A receiving portion of the crash beam receiver 160 may be hollow such that the crash beam 102 is inserted therein for coupling the two components. The crash beam receiver 160 may be coupled to a crash wall 180 which may be the same as or different than the vehicle firewall. The crash wall 180 may be anchored to the body structure and/or chassis of the vehicle causing a portion of the energy received by the crash wall 180 to be transferred to the body structure and/or chassis. In some embodiments, the front region of the electric vehicle 100 is symmetrical in the lateral direction such that the electric vehicle 100 comprises two parallel crash beams and two of each of the surrounding components.

FIG. 3 illustrates a perspective view of the crash beam 102, according to an embodiment of the present disclosure. In some embodiments, the crash beam 102 includes multiple outer sides, including a left side 104, a top side 106, a right side 108, and a bottom side 110 that are coupled together and extend in the longitudinal direction. In some embodiments, these sides are directly coupled together forming a rectangular cross section. In other embodiments, they are indirectly coupled together via one or more diagonal sides 120. In some embodiments, the diagonal sides 120 form 135 degree angles with respect to each of the left side 104, the top side 106, the right side 108, and the bottom side 110.

The crash beam 102 may include one or more impressions 122 positioned along the outer surface of the crash beam 102. In some embodiments, the impressions 122 are coupled to the diagonal sides 120 such that the impressions 122 may each include a concave facet positioned on the outer surface of the diagonal sides 120. The impressions 122 may be considered as being part of the diagonal sides 120 or as being a separate component coupled to the diagonal sides 120. The impressions 122 may have a length in the longitudinal direction that is less than the length of the diagonal sides 120 in the longitudinal direction such that each of the impressions 122 is localized to a specific region along the crash beam 102. Different impressions may be aligned or offset in the longitudinal direction. In general, the self-collapsing process of the crash beam 102 is improved where at least two of the impressions 122 are aligned in the longitudinal direction.

FIG. 4 illustrates a front view (and cross-sectional view) of the crash beam 102, according to an embodiment of the present disclosure. In some embodiments, the crash beam 102 includes four diagonal sides 120 and four impressions 122. In some embodiments, the impressions 122 may be coupled to one of the diagonal sides 120 and to the two adjacent sides.

For example, the impression 122 a is coupled to the diagonal side 120 a and to the left side 104 and the top side 106. In some embodiments, the concave portion of the impressions 122 may extend inward toward the center of the crash beam 102 at a greater depth than is shown in FIG. 4. Increasing the depth of the impressions 122 improves the self-collapsing process of the crash beam 102 at the cost of decreased rigidity and decreased absorption of energy.

In some embodiments, the crash beam 102 includes a center rib 114 extending in the vertical direction between the top side 106 and the bottom side 110, the center rib 114 being coupled to both. The center rib 114 extends in the longitudinal direction parallel to the left side 104 and the right side 108. In some embodiments, the center rib 114 has a smaller thickness than the outer sides of the crash beam 102 to improve the self-collapsing process of the crash beam 102. In some embodiments, the center rib 114 has the same thickness as the outer sides of the crash beam 102 but is derived from a weaker material than the outer sides. In some embodiments, the center rib 114 is positioned such that it is centered with the crash beam 102 in the lateral direction.

In some embodiments, the crash beam 102 includes an upper cross rib 116 extending in the lateral direction between the left side 104 and the right side 108 and extending in the longitudinal direction parallel to the top side 106 and the bottom side 110. In some embodiments, the crash beam 102 includes a lower cross rib 118 extending in the lateral direction between the left side 104 and the right side 108 and extending in the longitudinal direction parallel to the top side 106 and the bottom side 110. The upper cross rib 116 and the lower cross rib 118 improve the self-collapsing process of the crash beam 102, increase the rigidity of the crash beam 102, and increase the absorption of energy of the crash beam 102 in the event of a vehicle collision. In some embodiments, the upper cross rib 116 and the lower cross rib 118 are spaced evenly in the vertical direction such that they are equidistant from each other and from the top side 106 and the bottom side 110. In some embodiments, the upper cross rib 116 and the lower cross rib 118 are not spaced equidistant but are both positioned below a vertical half way line of the crash beam 102 so that energy is channeled in the downward vertical direction in the event of a vehicle collision.

FIG. 5A illustrates a front view of the crash beam 102, according to an embodiment of the present disclosure. In some embodiments, the crash beam 102 includes one or more spacing structures 124 coupled with the center rib 114, the upper cross rib 116, and the lower cross rib 118. One purpose of the spacing structure 124 is to improve the self-collapsing process of the crash beam 102 by allowing the crash beam 102 to flatten linearly. For example, during the self-collapsing process a hollow core may be formed within the crash beam 102 that may, in some circumstances, cause the crash beam 102 to contort at an angle. The spacing structure 124 lessens this effect by filling the hollow core that is formed during the self-collapsing process. The spacing structure 124 may be planar and may extend in the lateral direction and in the vertical direction. The spacing structure 124 may be rectangular, square, circular, or of some other shape.

FIG. 5B illustrates a side view of the crash beam 102, according to an embodiment of the present disclosure. FIG. 5B illustrates the embodiments in which the spacing structures 124 and the impressions 122 include multiple layers that are offset in the longitudinal direction, which may improve the self-collapsing process. In some embodiments, different layers of the spacing structures 124 and the impressions 122 are aligned with each other in the longitudinal direction. In some embodiments, the crash beam 102 includes only a single layer of impressions 122 and a single spacing structure 124 that is aligned with the single layer of impressions 122.

FIG. 6 illustrates a front view of the crash beam 102, according to an embodiment of the present disclosure. In some embodiments, the crash beam 102 includes additional internal structures to improve the self-collapsing process. For example, in some embodiments, the crash beam 102 includes an inner left side 126, an inner top side 128, an inner right side 130, and an inner bottom side 132. In some embodiments, these sides are directly coupled together forming a rectangular cross section. In other embodiments, they are indirectly coupled together via one or more inner diagonal sides 134. The crash beam 102 may include one or more inner impressions 136 coupled to the inner diagonal sides 134 and the two adjacent sides, similar to the configuration of the impressions 120. In some embodiments, both the inner left side 126 and the inner right side 130 include two separate non-coupled components such that a hollow center portion of the crash beam 102 between the upper cross rib 116 and the lower cross rib 118 is preserved.

FIG. 7 illustrates a front view of the crash beam 102, according to an embodiment of the present disclosure. In some embodiments, both the inner left side 126 and the inner right side 130 extend between the upper cross rib 116 and the lower cross rib 118.

FIG. 8A illustrates a front view of the crash beam 102, according to an embodiment of the present disclosure. In some embodiments, the spacing structure 124 may be coupled to one or more of the inner left side 126, the inner top side 128, the inner right side 130, the inner bottom side 132, and the inner diagonal sides 134. In some embodiments, the spacing structure 124 has the same shape as the combination of the inner left side 126, the inner top side 128, the inner right side 130, the inner bottom side 132, and the inner diagonal sides 134.

FIGS. 8B and 8C illustrate a side view of the crash beam 102, according to various embodiments of the present disclosure. In some embodiments, each of the impressions 122, the inner impressions 136 and the spacing structures 124 include multiple layers that are offset in the longitudinal direction, which may improve the self-collapsing process. In some embodiments, each layer of impressions may be separated by the spacing structures 124 (as shown in FIG. 8C). In some embodiments, different layers of the impressions 122, the inner impressions 136 and the spacing structures 124 are aligned with each other in the longitudinal direction.

FIG. 9 illustrates a method 900 for receiving an impact force related to a vehicle collision, according to an embodiment of the present disclosure. At step 902, a vehicle collision occurs. The collision may be a head-on (front), side, or angled impact, or an impact from some other direction. At step 904, the top side 106 receives a first force related to the impact force. At step 906, the right side 108 receives a second force related to the impact force. At step 908, the bottom side 110 receives a third force related to the impact force. At step 910, the left side 104 receives a fourth force related to the impact force. At step 912, a first portion of the first force received by the top side 106 is transferred to the diagonal sides 120. At step 914, a second portion of the second force received by the right side 108 is transferred to the diagonal sides 120. At step 916, a third portion of the third force received by the bottom side 110 is transferred to the diagonal sides 120. At step 918, a fourth portion of the fourth force received by the left side 104 is transferred to the diagonal sides 120. At step 920, a fifth portion of the force received by the diagonal sides 120 is transferred to the impressions 122. In some embodiments, method 900 further includes a step in which the impressions 122 are caused to fold in the longitudinal direction such that a forward side of the impressions 122 comes into physical contact with a rearward side of the impressions 122.

FIG. 10 illustrates a perspective view of the front region of the electric vehicle 100, according to an embodiment of the present disclosure. In some embodiments, the shock tower 190 is designed to be as stiff as possible while preserving the functions of the crash beam 102 and the crash beam receiver 160. To accomplish this, three specifically designed connections between the shock tower 190 and the crash beam 102 and the crash beam receiver 160 are provided. The front securement member 194 is attached to the crash beam 102 along the lateral sides of the crash beam 102 (left side 104 and right side 108) but not along the top or diagonal sides of the crash beam 102. By not attaching to the top of the crash beam 102, in the event of a vehicle collision, undesirable vertical torques to the crash beam 102 by the front securement member 194 may be avoided. Furthermore, the front securement member 194 is attached to the sides of the crash beam 102 along a line parallel to the longitudinal direction, thereby further reducing undesirable torques. In some embodiments, the front securement member 194 is not coupled directly to the crash tower 190 but is coupled to a longitudinal beam 192 which is coupled to the crash tower 190.

Similar to the design of the front securement member 194, the middle securement member 195 is also attached to the crash beam 102 along the lateral sides but not the top or diagonal sides of the crash beam 102. The attachment of the middle securement member 195 differs from that of the front securement member 194 in that the attachment area is not linear but rather includes a square or rectangular area along the left side 104 and the right side 108 of the crash beam 102. The possibility of undesirable torques is lessened for the middle securement member 195 due to its proximity to the crash beam receiver 160, thus a stronger attachment may be employed. The rear securement member 196 is attached to the crash beam receiver 160 at the top of the crash beam receiver 160 through a large attachment area. In some embodiments, the shock tower 190, the middle securement member 195, and the rear securement member 196 are comprised from a single material.

FIG. 11 illustrates a perspective view of the crash beam receiver 160, according to an embodiment of the present disclosure. In some embodiments, the crash beam receiver 160 includes a plurality of surfaces that are coupled together to form a hollow opening for receiving the crash beam 102. The plurality of surfaces may include a left surface 162, a right surface 164, a top surface 174 (not shown in FIG. 11), a bottom surface 176, and one or more diagonal surfaces 178. The plurality of surfaces may be coupled together such that the crash beam 102 may be securely inserted into the hollow opening.

In some embodiments, the crash beam receiver 160 includes a gate structure 165 comprising a left gate 166, a right gate 168, and a protrusion structure 167. The gate structure 165 performs at least two functions. First, the gate structure 165 provides a stopping point for the crash beam 102 when it is inserted into the crash beam receiver 160. Second, the gate structure 165 has properties that allow it to linearize the self-collapsing process of the crash beam 102 in the longitudinal direction, as will be described in reference to FIG. 12 below.

FIG. 12 illustrates a top view of the crash beam 102 and the crash beam receiver 160, according to an embodiment of the present disclosure. In some embodiments, the gate structure 165 includes the left gate 166 which is coupled to the left surface 162 within the hollow opening. The left gate 166 extends toward the right surface 164 in the lateral direction but does not directly couple to the right surface 164. In some embodiments, the left gate 166 is also coupled to the top surface 174, the bottom surface 176, and to one or more of the diagonal surfaces 178. In some embodiments, the left gate 166 is narrower toward the right lateral direction and thicker toward the left lateral direction. In other embodiments, the left gate 166 has uniform thickness in the lateral and vertical directions.

In some embodiments, the gate structure 165 includes the right gate 168 which is coupled to the right surface 164 within the hollow opening. The right gate 168 extends toward the left surface 162 in the lateral direction but does not directly couple to the left surface 162. In some embodiments, the right gate 168 is also coupled to the top surface 174, the bottom surface 176, and to one or more of the diagonal surfaces 178. In some embodiments, the right gate 168 is narrower toward the left lateral direction and thicker toward the right lateral direction. In other embodiments, the right gate 168 has uniform thickness in the lateral and vertical directions. In some embodiments, the right gate 168 overlaps and covers a portion of the left gate 166 such that a portion of the left gate 166 is obscured from a view from the front longitudinal direction toward the back longitudinal direction (as shown in FIG. 13). In some embodiments, a spacing exists between the left gate 166 and the right gate 168 such that they are not in physical contact with each other. In other embodiments, the left gate 166 and the right gate 168 are in physical contact with each other.

In some embodiments, the gate structure 165 includes a protrusion structure 167 positioned along the edge of the left gate 166. The protrusion structure 167 extends outward in the longitudinal direction from the left gate 166 and has a certain thickness. The thickness of the protrusion structure 167 may be determined such that the crash beam 102 may come in physical contact with the protrusion structure 167 and the right gate 168 simultaneously in the event of a vehicle collision. The protrusion structure 167 may be positioned along the entire edge of the left gate 166 or along some portion of it. In some embodiments, the protrusion structure 167 is positioned at the interface between the left gate 166 and the left surface 162 such that the protrusion structure 167 is coupled to both the left gate 166 and the left surface 162. The width of the protrusion structure 167 in the lateral direction is ideally greater than or equal to the width of the left side 104 of the crash beam 102, but not too wide to reduce the flexibility of the left gate 166.

In some embodiment, the gate structure 165 improves the self-collapsing process of the crash beam 102 by forcing the collapsing crash beam 102 to collapse inward toward the center rib 114. In the event of a vehicle collision, a head-on impact force pushes the crash beam 102 in the rearward longitudinal direction. The left side 104 and the right side 108 of the crash beam 102 come in contact with the gate structure 165 prior to the center rib 114 contacting the right gate 168, causing the left side 104 and the right side 108 to collapse inward toward the center rib 114. This process is enabled by (1) the left surface 162 and the right surface 164 extending past the gate structure 165 in the forward longitudinal direction, (2) the overlap of the left gate 166 and the right gate 168 being offset from the protrusion structure, and (3) the flexibility of the overlap of the left gate 166 and the right gate 168.

In some embodiments, the design of the crash beam receiver 160 is flipped in the lateral direction such that the protrusion structure 167 is positioned along the edge of the right gate 168 and the left gate 166 overlaps and covers a portion of the right gate 168 such that a portion of the right gate 168 is obscured from view. In some embodiments, the crash beam receiver 160 includes one or more wall structures 170 that form apertures along the center of the crash beam receiver 160 in the lateral direction. Multiple layers of the wall structures 170 may be positioned behind the gate structure 165. The wall structures 170 help to maintain the linearity of the self-collapsing process of the crash beam 102.

FIG. 13 illustrates a front view of the crash beam receiver 160, according to an embodiment of the present disclosure.

FIG. 14 illustrates a top view of the crash beam 102 and the crash beam receiver 160, according to an embodiment of the present disclosure. In some embodiments, the wall structures 170 a and 170 b may couple together at the center of the crash beam receiver 160 in the lateral direction. In some embodiments, a cantilever structure 172 may be attached to the wall structures 170 and may extend outward in the forward longitudinal direction toward the gate structure 165. The cantilever structure 172 may initiate a bending process of the wall structures 170 to help maintain the linearity of the self-collapsing process of the crash beam 102. The length of the cantilever structure 172 in the longitudinal direction may be based on the distance between the wall structures 170 and the gate structure 165 in the longitudinal direction and on the lengths of the left gate 166 and the right gate 168 in the lateral direction.

FIG. 15 illustrates a method 1500 for receiving an impact force related to a vehicle collision, according to an embodiment of the present disclosure. At step 1502, a vehicle collision occurs. The collision may be a head-on (front), side, or angled impact, or an impact from some other direction. At step 1504, the crash beam 102 receives a first force related to the impact force. At step 1506, a first portion of the first force received by the crash beam 102 is transferred to the right gate 168. At step 1508, a second portion of the first force received by the crash beam 102 is transferred to the protrusion structure 167. At step 1510, a third portion of the force received by the right gate 168 is transferred to the left gate 166. At step 1512, a fourth portion of the force received by the protrusion structure 167 is transferred to the left gate 166.
